RAIN-WATER FILTER.

SPECIFICATION forming part of Letters Patent No. 571,776, dated November 24, 1896.

Application filed May 9, 1896:

To rtZZ whom 71mg concern-.-

lie it known that I, NATHAN H. LONG, a citizen of the United States, residing at Muncie, in the county of Delaware and State of Indiaria, have invented certain new and useful Improvements in Rainater Filters; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use thesame.

This invention relates to improvements, as hereinafter set forth, in rain-water filters adapted to be'attaehed to a building in connection with the rain-spout or gutter.

In the accompanying drawings, Figure l representsa perspective view of myimproved filter. Fig. 2 represents a sectional side elevation thereof.

The object of my present invention is to produce an improved filter adapted to be reinovably connected at its upper portion to the ordinary rain-conveying spout depending from the eaves or roof-gutter of a building, and connected, with capability of ready re moved, at its other end with a suitable cistern or tanlgavithin which the filtered rainwater is received. The construction shown in the drawings, and to be presently described, results in the production of a filter which, while cheap in construction and capablc of being readily placed in and removed from position, is automatically self-cleaning, automatically discharges all dirt and other foreign matter that may wash off the roof, and requires no filtering material other than the construction of the apparatus to secure the thorough filtration of the water passing through the apparatus.

1 represents the main chamber or body of the apparatus. This, as shown, is of vertical formation with a Vertically-flat rear or back 2 to adapt it to rest againstthe wall or side of a house or other building, so as to be braced and steadied thereby.

3 represents a laterally-extendin g flange, of which there are two, one extending from each side edge of the body 1, having a vertical slot 4, through which is passed a screw 5 or other suitable device for removably and ad- $erial No- 590,893. (No model.)

justably attaching the apparatus to a building.

The body 1 may be of any suitable metal or material, and has, preferably, its front upper portion extending angularly forwardly and downwardly, as shown at 6, and from thence in a rearwardly angular direction, as shown at 7, whereby sufiicient space is pro vided at its upper portion to receive the water-filtering and dirt-discharging shoe, to be presently described, and to provide space for containing the reticulated filtering cylinder or tube and for receiving and guiding the water to said filtering cylinder or tube.

8 represents the water-filtering and dirtdischarging shoe, which is independent of and removably contained within the upper, widest, portion of the body or chamber 1. This shoe may be retained in position, with capability of ready removal, in any suitable manner, as, for instance, by means of an upturned flange 9, extending from the hood 10 and engaging with a flange 11, extending downwardly from the top 12 of the body portion 1, and a downcurved flange 13 at its lower front edge gripping the front edge 14 of the body 1. This shoe has imperforate side walls 15, which snugly it the inner sides of the body 1, and a concave and upwardly curved rear reticulated portion 16, and a forwardly and downwardly curved reticulated forward portion 17.

18 represents an upward extension dividing the reticulated portions 16 17 of the shoe and serving as a dam which, in connection with the flap or shutter 19, hinged at 20, operates tocheck the flow of water when the downfall is excessive. This dam also acts as a separator or stop for the dirt falling onto the shoe, the hinged shutter 19 being, however, suiiiciently raised to permit of the inflow of water forcing the accumulated dirt across the frontportion of the shoe and over the front edge thereof onto the ground. By the use and location of the flap or shutter, as shown, the same serves the additional purpose of preventing the descending water splashing out over the front of the shoe, but confines it measurably to the reticulated portion ofthe shoe, so that it may descend into the chamber.

21 represents one of a pair of hooks connected with the flap or shutter, said hooks engaging with eyes 22 to hold said shutter or flap and also aid in securing the shoe in posiiilOll.

23 represents a vertical reticulated cylinder or tube frictionallysupported at its lower end 24: in the tube or pipe 25, through which the filtered water passes to the cistern or other receptacle. (Not shown.) This reticulated cylinder or tube 23 serves to additionally filter the water which has been preliminarily filtered in its passage through the shoe 8, as all the water passing into the discharge-pipe 25 must first pass through said cylinder 23, as clearly indicated in Fig. 2.

26 represents a collar extending vertically upward from the top 12 of the chamber or body 1 to receive and gripping] y hold, as shown in Fig. 2, the lower endof a bifurcated or two-part pipe. Of this 26 represents the section of said pipe through which water passes from the upper section 27, which connects with the pipe (not shown) connecting with the gutter for carrying oifthe rain-water therefrom. The pipe-section. 28, branching from the section :26, represents the wastewater-discharge pipe through which the rain: water discharging from the gutter or eavestrough passes when the cistern is full or when for any other reason it is not desired to pass water through the filter.

20 represents a valve or shutter of preferably curved form, as shown, pivoted in the upper portion of the sectional pipe and operable by a handle or rod, as 30, to turn said valve in either direction desired to close either section of said pipe, as shown in dotted lines in Fig. 1, to permit of the water deseending from the roof passing down either branch 26 or 28 of the filter-supply pipe, as it may be desired to carry such water either into the filter or through the waste-pipe.

Having thus described my invention, what I claim is- 1. A rain-water filter, consisting of a chambered bodyportion adapted to be attached to a building, a pipe connecting said chambered body and the rain-water-supply pipe, a discharge-pipe connected with the lower portion of said body, a vertical reticulated chamber or tube seated in said discharge-pipe and ex tending up within said chamber, a shoe removably seated in the upper portion of said chambered body and having at its upper portion a depending hood, a dual-concaved and reticulated lower portion constituting the bottom and rear, an upwardly-extending dam between said dual eoneaves, and a shutter hinged on, said shoe and roekin g] y depending above the reticulated portion thereof substantially as and for the purpose set forth.

2. A rain-water filter, consisting of a chainbered body portion adapted to be attached to the side of a building and having at its top an upwardly-extending collar and at the upper portionof its front face an opening and a depending flange, a double-concaved rctic tubular strainer removably seated in said discharge-pipe and extending up within said chamber, substantially as and for the purpose set forth.

3. A rain-water filter adapted to be attached to a building and having connection with the rain-water supply, and consisting of a shell or body and an outlet-pipe, a vertically-disposed chamber located within said ,shell or body and a shoe'remova'bly seated in the upper portion of said shell or body and having a reticulated bottom portion and a transverse bridge, or dam, and a shutter rockingly journaled in said shell and extending transversely of and above :said shoe, substantially as and for the purpose set forth.

at. A rain-water filter, consisting of a shell or body having a fiat rear portion and a downwardly-tapering front portion, a water-discharge pipe connected with its lower end, a reticulated cylinder or tube removably seated at its lower end in said discharge-pipe, a shoe removably seated in the upper portion of said shell and having a dual-concaved reticulated bottom and a substantially central upwardlyprojecting bridge or dam, a shutter pivoted in said shell and located above'said bridge or dam, a combined watersupply and wastedischarge pipe connected with the upper portion of said shell, and a cut-off valve located in said last-named pipe substantially as and for the purpose set forth.

In testimony whereof I affix my signature in presence of two witnesses.
